Approaches towards a generic methodology for storage of hazardous energy carriers and waste products

Energy carriers – either conventional or ‘new’ ones – have to be provided in large amounts to meet the requirements of permanent availability and reliable supply of electricity. Depending on their state of aggregation, energy carriers are either stored in large masses (if solid or liquid) or at elevated pressures (if gaseous). Both impose the hazard of large-scale fire, in the latter case additionally the danger of explosion or unintended release. Very similar hazards occur for wastes. Solid wastes are present in large masses and only a small part is recycled. Most of the solid wastes are used in energy conversion. The main gaseous waste is CO₂. During capturing also the hazard of unintended release exists. In this article, existing approaches for safe storage and fire prevention are discussed and a generic methodology is outlined. This methodology consists of the following steps:

? gaining knowledge about the behaviour of the material stored (reactivity, thermal stability, etc.),

? assessing the environmental conditions for the storage site (neighbourhood, safety distances, etc.),

? assessment of prospective consequences of an incident and

? development of individual loss prevention conceptions.

All steps require both experimental testing and theoretical considerations about accident scenarios as integral parts of the methodology.     

LATEST DEVELOPMENTS IN LOCAL GOVERNMENT ACCOUNTING IN SPAIN

This paper provides an analysis of the present situation concerning local government accounting in Spain following recent reforms introduced in the early nineties. It presents a picture of the main features of Spanish local finance—budgeting and accounting, the measurement focus, and the basis of accounting—and analyses the financial reporting system adopted by Spanish municipalities. This is followed by a critical review of several weak points in the reform which in the author's view will encourage further developments.     

Experience and the unexpected: risk and mitigation issues for operating underground storage silos for coal-fired power plant

Observed autoignition events and extinguishing the resulting smouldering fires in an underground storage system of a coal-fired power plant have provided insight into the array of contributing variables, and some experience on quantifying the risk with alternative scenarios of event initiation, progress and potential mitigation. Although the first attempts to quantify the risk suggest high sensitivity to the sequence of action taken after fire alarm, and no similar storage sites really exist, some recommended preventive, corrective and other mitigating activities can be at least partly defined and improved by using the cumulative experience and parallel efforts in other closed or underground storage sites. However, there are also so-called black (or at least grey) swans: unexpected events for which the facility may be poorly prepared for. In the case of the underground storage silos, such an event was experienced when incoming cold coal during a harsh winter season froze the sewer system that normally protects the stored coal from seepage water. With blocked normal bypass, the seepage water found its way to the coal silos and created large clumps of icy coal that blocked the coal conveyors. Although freezing weather is not unusual at high-latitude power plants, the common methods to combat freezing of coal are mainly useful for open storage sites and above-ground transport. Options for mitigation are discussed, as well as the event chain leading to an event that had never previously occurred. The case is discussed from the point of view of options to prepare for rare or unforeseen events.     

Organizational Surveillance of Computer-Mediated Workplace Communication: Employee Privacy Concerns and Responses

Email, social media, and other types of computer-mediated workplace communication tools can enhance flexibility in how employees perform their jobs, expand networking opportunities, increase profits, cut costs, and enable collaboration among diverse groups across the globe. Despite their advantages, these technology tools can also cause security breaches, financial loss, employee distraction, and lawsuits. To prevent such damaging consequences, many companies monitor their employees’ computer-mediated workplace communication. However, this surveillance is often met with resistance from employees as it taps into concerns over workers’ privacy rights, due process, and fairness. We examine these employee concerns through an empirical study of full-time working adults’ beliefs about their computer-mediated workplace communication privacy and their evaluations of organizational justice, trust in upper management, and commitment to the organization. Our results suggest that employees who perceive less computer-mediated workplace communication privacy tend to view their organization’s policies as less fair, trust upper management less, and demonstrate less commitment to their organizations. Furthermore, results indicate that procedural justice mediated the relationship between privacy and organizational commitment and moderated the relationship between privacy and organizational trust.     

TOWARDS AN ALGORITHMIC REVOLUTION IN ECONOMIC THEORY

Abstract This is an attempt to tell a coherent story of a possible path towards an algorithmic revolution in economic theory, based on foundational debates in mathematics. First, by exposing the non‐computational content of classical mathematics, and its foundations, it is shown that both set theory and the tertium non datur can be dispensed with, as foundational concepts. Next, then, as a natural sequel, it follows that every kind of economic theory that bases its theoretical underpinning on classical mathematics can be freed from these foundations and can be made naturally algorithmic. This will make the subject face, in an all pervasive way, absolutely (algorithmically) undecidable decision problems. The thrust of the path towards an algorithmic revolution in economics lies, then, in pointing out that only a radically new mathematical vision of microeconomics, macroeconomics, behavioural economics, game theory, dynamical systems theory and probability theory can lead us towards making economic theory a meaningfully applied science and free of mysticism and subjectivism.     

The Dynamics of Labour Flexibility: Relationships between Employment Type and Innovativeness

This paper investigates the relationship between flexible human resource (HR) practices and innovativeness. Testing the research model in a sample of first‐tier automotive suppliers indicates that internal flexibility practices are positively related to innovativeness. Regarding external flexibility, the association depends on the type of contingent employee: negative association for ‘short‐term hires’ and positive association for ‘consulting/contracting firms’. The relationships to innovativeness for practices associated with knowledge transfer are moderated by environmental dynamism, but the non‐knowledge related practices are not. Firms in highly dynamic environments can benefit more from flexible HR practices than firms in less dynamic environments.     

NON‐LINEAR DYNAMICS,COMPLEXITY AND RANDOMNESS: ALGORITHMIC FOUNDATIONS

Abstract In this paper I make an attempt to describe, discuss and extend a few aspects of the rich mathematical tapestry that can be woven with rigorous notions of non‐linear dynamics, complexity and randomness, in terms of algorithmic mathematics. It is a tapestry that I try to weave with economic analysis, economic theory and economic modelling in mind. All three notions – that is, non‐linear dynamics, complexity and randomness – have a rich conceptual, modelling or analytic tradition in core areas of economic theory, both at the micro and macro levels. It is the algorithmic foundation I try to provide for them that could be considered the novel contribution in this paper. Once the algorithmic foundations are in place, it is, for example, almost natural to consider the famed difficulties of obtaining closed form solutions for non‐linear, complex or random dynamic models in economics almost a trivial vestige of a pre‐simulation era in mathematical modelling.     

A disequilibrium macrodynamic model of fluctuations

A non-linear disequilibrium macrodynamic model of fluctuations in the labour and product markets, mediated by variations in factor shares, is developed and the existence of a periodic orbit is proved using the Hopf bifurcation theorem.
